I am working on Windows Phone 8 application development both hybrid/native. In terms of hybrid I have good exposure on HTML5/CSS, JavaScript, JQuery and PhoneGap (Cordova Framework) and in terms of natve I am working on xaml/c#/sqlite/MVVMCross

With so many limitations in Windows Phone 8 for hybrid applicaitons I am having good experience in developing application in windows phone 8 which are already there in Android and iOS.
